Agilent ZORBAX RRHD Bonus-RP Column Separating Basic and Highly Polar Compounds
The Agilent ZORBAX Rapid Resolution High Definition (RRHD) threaded columns are designed specifically for use with ultra-high performance liquid chromatographs (UHPLCs). The Bonus-RP variant features a unique combination of densely reacted, sterically protected diisopropyl-C14 groups covalently bonded through an embedded amide functionality to an ultra-pure ZORBAX Rx-SIL silica support. This design reduces strong interactions of basic and other highly polar compounds.

They are specially designed for use with ultra-high performance liquid chromatographs (UHPLCs) such as the Agilent 1290 Infinity LC.
It is designed to reduce or eliminate strong interactions of basic and other highly polar compounds.
No, column stability at pH > 6 is enhanced by avoiding phosphate and carbonate buffers.
